HCSE Provide Benefits of Bim

Most importantly, BIM is not a technology. It is a

process. This is possibly the most important

aspect to understand. BIM applies to all aspects

of the construction of a building, from the design,

the estimating, the supply chain, the delivery of

goods during the build, the build process, the

resource allocation, the productivity requirements

to meet targets and on in to the post-handover

phase through Facilities and Asset Management.

Aspects of BIM are enabled through various

technology platforms. There are several providers

of technology which supports architectural tools

plus the addition of intelligent information against

the model. Examples include Autodesk Revit,

Graphisoft ArchiCAD 17, 12d Model and Synchro

Professional.

BIM has several implementation levels:Level 0:

CAD using drawings, lines, arcs, text, etc. Level 1: 2D & 3D using models, objects plus file based

collaboration

Level 2: BIMs plus file based collaboration and library

management for models and objects and

Level 3: iBIM, Lifestyle Management, common dictionaries,

data and processes underpinned by integrated and

interoperable data through web services

Level 2 BIM is often seen as the minimum

standard to achieve. These levels are also split in

to A and B, e.g. 2A and 2B which denotes the

directionality of information sharing, i.e. one-way

or multi-way. Here are two diagrams explaining

the differences:

Industry Foundation Classes (IFC) and COBie are standards used toshare information. IFCs describe building and construction industrydata. It is a platform neutral, open file format developed by buildingSMART to facilitate interoperability in the architecture, engineering andconstruction (AEC) industry. COBie is a data format for the publicationof a subset of building model information focused on delivering buildinginformation and not geometric modelling. It is closely associated withBIM and is typically exchanged using XML. These formats enable BIMinteroperability and all BIM software is able to consume thisinformation. Most are able to write it, enabling the sharing ofinformation, even at Level 2 BIM to be easily achieved. Externalsoftware such as Safe Software Feature Manipulation Engine (FME) isable to transform from IFC and COBie to other formats. This representsthe beginnings of full integration possibilities between BIM and GIS.

BIM is so much more than just a detailed 3D model of a building.

The concept is most easily explained by the term build 4

times which means build three times in the model and once on the

ground. The accuracy of the model combined with animations and

fly-throughs allow contractors to access the design layout before the

build takes place and make alterations. This means that when the

build takes place, there are fewer errors and far less rework

needed. This moves the construction procurement process from

design and build to design build by bringing the construction team

in to the design process rather than them simply having to respond

to a tender for construction after the design has been completed.

Parametric Modelling is a key principle of BIM. Essentially this

means that everything in the model is connected to everything

else. If you move the location of a wall, the elements attached to

the wall also move. If you change the volume of a floor, the

quantities of material needed to lay the floor alter. If you move

ducting in the ceiling, all aspects associated with the ducting

update and conflicts are highlighted. This is also true for BIMs that

have been developed independently and brought together in a

collaborative BIM environment. This allows organisations who may

be controlling different elements of the build to benefit from one

another as aspects of the model are altered through the process.

Change once, benefit many times.

The 'D' elements of BIM relate to the

information associated with the model.

4D relates to scheduling information; when will an elementbe built. With this information you can enable just-in-time(JIT) delivery of materials to site. This in turn has an impacton transportation, making it more efficient, and reducesstorage issues as materials are delivered and immediatelyinstalled.

5D relates to the estimating and cost aspects of the building.Each element within the building model has a cost associatedwith it. This allows for detailed analysis to be done regardingbudgets. It also allows the delivery team to make accuratepredictions regarding how much needs to be done at anygiven time in order to meet the construction targets.

6D covers the sustainability targets for a building allowinginformation such as energy use, sustainability from amaterials and management point of view to be understoodand Leadership in Energy and Environmental Design (LEED)tracking to be performed.

7D is the "as-built" BIM model which is important as part ofthe handover process to the building owner. This model is afundamental part of the ROI for BIM as it provide accurateFacilities Management (FM) and Asset Management (AM).Each part within the building will have a lifespan and in theevent of replacement, the easy identification of parts ensuresthat these processes may be performed efficiently.

BIM enables new procurement processes to take place whichdeliver certainty to all parties involved. A typical process mightlook like this:

The design and construction teams are selected

The design work is done and is reviewed by the construction team andother subject matter experts. This review identifies areas of rework.

This process iterates 2 more times, the result is the best possibledesign.

Generic objects may have been used for materials and/or equipment;these may now be replaced by specific models conforming to the IFCclasses with known materials, costs and supply chain informationassociated with them. In this way, the full cost of the building, thesuppliers and supply chain costs of materials and the installationmethodology is known by everyone involved.

The work can now start on site using the BIM to direct the build.Technology assists in the build by presenting the BIM information in thefield as construction takes place. JIT delivery of materials keeps buildingefficient.

Governments around the world are now realising the benefits of

BIM, especially for large construction funded with public money,

and are beginning to mandate the use of BIM for these projects.

When has that ever happened for GIS? The effect of this is to

seed the industry to change. The reality is that the industry is

moving this way anyway as they have already recognised the

advantage of using BIM. The issue has been the slow adoption

of the client to realise the benefits of the BIM approach – to the

point that some are still rejecting the final as-built BIM model,

considering it an unnecessary cost rather than realising that it

will reduce the AM/FM costs of running the building. Given that

government is often the client, it would appear that this is

actually an internal issue between government agencies or even

roles with the same government agency that needs to be

resolved as quickly as possible.

The result of BIM is impressive
